Hands on Boiler Training: A Dream to Reality

by on Apr.11, 2017, under News

GCAP is now moving on their 15 year of Hands-On Training.  In 2008 the school branched out and developed a new engine room for hands on training.  This ended up being 5 live boilers and the largest hands on training lab for boilers and steam in the industry.  Due to demand, GCAP has been in an expansion for Boiler Room number 2 that last few months.

Training Dates are available at this link

Boiler Lab # 1: A dream of 5 Steam Boilers in 2008 for hands-on-training


Boiler Lab #1: 5 Steam Boilers for Training

A dream of Boiler Room number 2 is coming true

Boiler Lab # 2: Early 2017

Advanced RETA Refresher

by on Mar.15, 2017, under News

New Course Available

GCAP’s Advanced RETA Refresher Competencies 


Prerequisite: Suggest prior Ammonia Operator 1 and/or Ammonia Operator 2 Credentials

This class is designed to be a refresher for any individual that is looking to attempt RETA Certification credentials such as the CARO (Certified Assistant Refrigeration Operator) or the CIRO (Certified Industrial Refrigeration Operator).  Individuals can also take this class as an overview refresher without sitting for the exams.

If a student was to take GCAP’s Ammonia Operator 1 Course that would be preparing for the CARO.  If a student was to take GCAP’s Ammonia Operator 2 Course that would be preparing the the CIRO and would be no need to take this class if sitting for those exams following the particular course.  This course is for individuals whom have have past experience, training and are now trying to sit for the exams and would like a review/refresher before taking the test. Also, many certifications/licenses across the country require continue education credits.  This class can meet what most require.

We suggest that you bring you past Ammonia Operator 1 and 2 books be supplemented with the book “Seeing Industrial Refrigeration from the Inside Out”. The class will be studying from multiple sources to prepare for the optional certification(s).  If you don’t have any prior books contact our office.

GCAP will provide several supplemental handouts, refresher exams,  study questions, and  RETA’s Online practice exam for the CARO/CIRO exams.  Participants will have the option of sitting for the RETA CARO or CIRO Examination on the last day of class  (must meet RETA requirements for testing). For RETA requirements and testing fees please contact our office.

Alfa Laval donates U-Turn Heat Exchanger to GCAP

by on Mar.06, 2017, under News


Danny Hauenstein and Jeremy Williams

This last week in San Antonia Texas, Alfa Laval was showcasing their partially flooded U-Bend / U-Turn plate and frame heat exchanger.  Since ALfa Laval showcased this a few years back the crew at GCAP has had to have one.  Danny Hauenstein made it happen this week and it’s is getting shipped to Kansas.  We have saved a special place for this unit in the hopes getting one for the training lab.


  • Compact dimensions
  • Shorter height and length allowing installation onsite without dismantling
  • No additional support is needed, as the U-Turn separator is supported entirely by the plate heat exchanger
  • Easy maintenance, as both sides of the plate heat exchanger are fully accessible.
  • All ammonia connections access the same side which makes installation easy
  • Integrated oil drain
  • Stainless steel ensuring corrosion resistance and no need of surface treatment
    YouTube Preview Image
  • It ensures efficient separation – due to the use of four different
    separation methods.
  • The short vertical ammonia driving columns, allowing small
    temperature approaches and high system efficiency.
  • Sliding support allows thermal expansion, ensuring no
    thermal tensions build up.
  • Significant oil pot volume in standard execution enough
    for manual drain
  • Separation based on droplet size 0.15 mm
  • Margin for separation is 25% plus one nominal diameter
  • Maximum separation gas velocity is restricted to 60% of
    the re-entrainment velocity, avoiding liquid brought back
    to the gas flow.
  • Extra safety margin from 180° U-bend.

New Book Coming Available

by on Dec.01, 2016, under News

GCAP’s Spanish Operator 1 book “Understanding Industrial Refrigeration from the Inside Out” has always been something we’ve wanted to offer to the industry. Anthony Verdugo and Miguel Bermudez have been challenged to translate GCAP’s English book completely into Spanish. Once the book is done, it will be used along with the Spanish lectures we offer in the Spanish Operator 1 course.   The goal is to have the book done and edited by April 2017!

When Anthony Verdugo came aboard in 2012, GCAP had the idea of developing a Spanish Division. Taking advantage of his bilingual abilities, he was given the responsibility to revise and re-edit the RETA Spanish book 1. After re-editing the RETA Spanish book 1, and developing Spanish lectures to go with it, we decided to launch our very first Spanish Seminar for Entry Level Operators. After doing a couple Spanish Seminars we realized that the material being presented was good, but the book wasn’t exactly what GCAP was trying get across to our students.

20161130_160729In 2015 GCAP decided to hire another Spanish Instructor, Miguel Bermudez was the perfect individual for the job. Therefore, Anthony and Miguel took the opportunity to begin converting the GCAP’s English book to Spanish.  A lot of hard work and dedication is being put into this book as we speak. “Translating an entire book to Spanish is not an easy task to do” said, Anthony Verdugo but “we look forward to offer a new Spanish Book for Entry Level Operators along with great Spanish lectures and the best hands on training lab in the U.S” said, Miguel Bermudez.  Once the book is completely done, we will be proud to announce that the Spanish Operator 1 Book “Understanding Industrial Refrigeration from the Inside Out” will be the new and improved textbook being used in our Spanish Seminars.

If you would like to get the book pre-ordered please give us a call @ 620.271.0037 or email us: ammonia@pld.com
